To all whom it may concern: I

B. i son, a citizen of the United States, at; a at Electra, in the county of Wichita an State of lexas, haveinvented new and iul improvements in Measures for @11- Wells, of which the folio fication. r I This invention relates to distance measuring instruments and more esially to those having a titcontact and a com puter; and the ohjectot the e is to roduce a device for ng the dep 0% oil and other wells by comyu un e mime-um I the hottom of the well.

As is well no to those art, the who ofthe depthoi' a Well with an 14M 6": steel ta haa weight on its end, is an arduous the weight and the tape when let out some distance weighing 150 pounds, and the weight a to pass arities of the well. As also is well 'own to them is with the business, the tools I h, the bottom, and when let down by a line the latter is paid out by machinery. we: to use the 1 to the Wei-man and o the e which would otherwise he coed inletting down and withdra 1- tachment for use in connection with the sand line ordinarily employed in the t": I r o eration, and when not in Details are set forth in the following made to the in which- F1gurc1 is'a side elevation of this device 1' for work. I 2 is a right end elevation; 4 Fig.3isaplanview. a In the drawings the numeral *1 designates a frame of t n, contour, perbags a foot long and I one or two inches wi e,-supported at its ends by 1 to the frameat 3 so that-they may be .foldedu ward whennot in use, as seen in doti ted es, and apgoriicatches inlay hold these legs in ed osition. At their lower ends the legs are widened into feet as best seen at 5 in Fig. 2 to give stability to rope or line as it dds for cetherehy sa la anat-U useitlaid legs2hinged fwardandthesp the frame when set up, and these feet rest on the floor ards l? at either side of the well so that the rope or line L may pass downward through the Inc at about the niidlength oi the latter. This line may carry a tool or a d, or any other object or instrument which is used in the ordinary course of in; the well, but oarily it is a rope which is at times withdrawn and at times let do, and the tape is used only occasionallyto ascertain depth. One side of the frame has a mot ahle section indicated at 6 in l, pivo at one end at 7 and fir of Letters Patent- Petented M og 2L 1M8 notched at e other end at 8, and this secable fastening device such as a thumb screw 9 which is set up to holdthe gate cl and the frame complete.

Through the e at one sideoi the gate ope is a 10 on which within the v 11.- is fix ii menu a contact wheel 11 whose circerence measures y one foot; and the shaft is 1 into the easing eta computer or regimr seen in 3 and 1 broadly hy the nuofthe structurea impot, er than it it r i for each rtion of the sh a one it), and

therefore its total increases in feet. e sides of the MW at the other side of the gate g -H 1W are S10 as at 13, and in the Slots .i

are sliably moun boxes 14 in which is shaft 15 oi other contact the tly curved 17 connects the boxes and I" :a-w:

At some time when a line is about to be, let down into the well, this deuice is brought and the yoke and its wheel move I contact w atthe passed through the open gate between the out, its legs 2 opened out as seenin full lines in Fig. 1, its gate opened, and the line L faces of the Wheels. The frame is now stood with its feet on the floor boards the gate closed and latched, and, he thum nut adjusted so that the lineis ently clamped between the two wheels. ow the well 'machinery is operated'to pay out on the line L rapidly. v As it passes between the wheels,

both rotate, and as the wheel 11 makes one rotation for each foot of line goingpast it, the computer or register is actuated accordingly. Wheli the tool strikes the bottom of the well, a proper computation can be made to ascertain the depthof the well, ifit be anoil well, in a manner which willbe clear.

'The wheel 16 is now retracted, the gate opened, the instrument removed v entirely from the line, its legs 2 folded and latched,

and the entire apparatus put away for future use; and thereafter the ordinary function of the "well machinery may be carried onwithout interruption.

What I claim as new, is-

A measuring device of the class described comprising a frame having an opening in one side, folding supporting legs for said frame, the side bars of the latter being slotted longitudinally at one side of said opening, boxes mounted in these slots, a shaft journaled in said boxes, a contact wheel mounted on said shaft, a yoke connecting saidboxes, a screw extending from the center of said yoke through the contiguous end of said frame, a nut on the screw outside such end, a spring coiled on the screw between the'end of the frame and center of the. yoke, a; second contact wheel journaled I in t e, frame at the opposite side of the o enin' therein -"a countin mechanism con- P g g nected with the last-mentioned wheel.
